Abstract

A method of making a flexible coaxial cable is provided. The method comprises advancing a cable core comprising a conductor and an expanded foam dielectric surrounding the conductor along a predetermined path of travel, directing an elongate strip of copper onto the advancing cable core and bending the copper strip into a generally cylindrical form so as to loosely encircle the core. Opposing longitudinal edges of the thus formed copper strip are then moved into abutting relation and a longitudinal weld is formed joining the abutting edges to thereby form an electrically and mechanically continuous tubular copper sheath loosely surrounding the cable core. The cable core and the surrounding sheath are simultaneously advanced while the tubular sheath is deformed into an oval configuration loosely surrounding the core. The longitudinal weld of the advancing sheath is then directed against a scarfing blade and weld flash from the sheath is scarfed from the sheath. The advancing copper sheath is sunk onto the advancing cable core to form the coaxial cable. A polymer composition may be extruded around the copper sheath to form a protective jacket surrounding the coaxial cable and may be bonded thereto. The present invention also includes a flexible coaxial cable having excellent electrical and bending properties.
